Abstract

An ambient condition detector incorporates a common radiant energy source to carry out a first, sensing, function and a second, information transmitting function. The source can generate a beam to implement a fire sensing function. In addition, modulated radiant energy emitted from the source can be remotely sensed to determine detector status or internal parameter values. In an alternate embodiment, a source of radiant energy can be configured at an exterior periphery of the detector and information can be wirelessly transmitted therefrom using one or more analog modulation processes.
